82 GREEN-HOUSE PLANTS. [MAY 



house plants which you plant out, than to take 

 up the old plants, as they never, in my opinion, 

 thrive when confined in pots, after being allow- 

 ed to grow freely, which they do when planted 

 in the borders; besides, the cuttings do not 

 occupy half the space of the old plants. 



The sorts I send are quite common ; and 

 should you not succeed with the cuttings, you 

 will replace them, next year, at a trifling ex- 

 pense. The prettiest plant among them is Cal- 

 ceolaria rugosa, which will be covered all the 

 summer with bright yellow flowers, which ap- 

 pear at first sight like little balls, till, on examin- 

 ing them, you see the reason why it is called 

 Calceolaria, or slipper wort. You need not 

 take cuttings of this plant till the autumn. 



You will admire, also, the Petunia nyctagini- 

 flora, which is very nearly allied to the to- 

 bacco plant, and is commonly called white 

 tobacco.
